The admin webui runs on the captain sub-domain so i'm not too sure if that can be firewalled.

How does any of that matter? Firewall the relevant port so that it only allows your connecting IP.

I haven’t used it but it appears to serve everything over the same port. You could block it with a reverse proxy but not with a firewall or layer 4 proxy.
